    Improvement of global report on bamboo resource through enhancing coordination for reporting and technical cooperation

    FAO Forest Resource Assessment (FRA) 2020 report, estimates 35 million ha of bamboo resources. Of the 132 countries that reported on bamboo, only 23, or 17%, indicated that they had bamboo resources. In 2020, fewer countries reported on bamboo coverage than in 2010, when 33 countries provided statistics. Importantly, out of the 7 countries supported by INBAR for assessment of bamboo resources during 2013-2018, only one country used the data for report, four countries did not report on bamboo resources and two countries provided outdated data. This indicates lacks of coordination among assessment and reporting agencies. INBAR has developed methodology for bamboo forest resource assessment (resource mapping; bamboo stock and carbon assessment) and on-farm bamboo resource. Furthermore, INBAR trained and supported its member states and wish to improve bamboo resource report in FAO FRA. This poster will showcase the global bamboo forest coverage, assessment methodologies, discuss challenges and opportunities for improving the bamboo component in FRA reports.

    Composition diversification vs. structure diversification: How to conciliate timber production and carbon sequestration objectives under drought and windstorm risks in forest ecosystems

    This article aims to compare different forest adaptation strategies from an economic perspective with the objective to reduce extreme drought- and windstorm-induced risks of dieback. In this study, two diversification strategies were analysed. The first one was composition-based and consisted of mixing beech with oak whereas the second one relies on a diversification of the structure through a shift from the even-aged to the uneven-aged structure. We tested the efficiency of these two strategies individually and then combined through a simulation study in which we evaluated the financial loss and the reduction of carbon sequestration capacity. We combined a forest growth model computing Monte Carlo simulations with a forest economic approach using the land expectation value (LEV) adapted for a stochastic setting. The maximisation of the LEV criterion made it possible to identify the most economically effective adaptation strategies. Results show that diversification increases timber production and LEV, but reduces carbon storage. The two risks as well as the adaptation strategies show some synergies. Trade-offs between the financial balance and the carbon balance (i.e., adaptation vs. mitigation) are achievable. Valuing carbon services in addition to timber ones increases the forest value. Finally, our study presents a new approach for the economic valuation of multi-risk forest management, highlighting the importance of investigating several risks in a common analysis rather than separately.

    Characteristics of sprouts occurrence by cutting to lower the stump height after harvesting the oak forest on the slope
    XV World Forestry Congress, 2-6 May 2022

    This study was conducted to suggest an improved cutting to lower the stump height after harvesting that can induce the occurrence of high-quality root sprouts considering the locational characteristics of oak forests distributed mainly on slope. The study site was established in where the location environment and the stump diameter distribution were similar. The stumps were cut (control area) low horizontally based on the top of the slope, and cut (treatment area) parallel to the slope and close to the ground. The average number of occurred sprouts per stump was eleven, and there was no difference between control and treatment. The amount of stump lateral sprouts was decreased by 38% in the treatment (4.3 sprouts/stump) compared to the control (6.9 sprouts/stump). The occurrence of root sprouts (control: 3.8 sprouts/stump, treatment: 6.5 sprouts/stump) increased by 171%. 79.5% of the control lateral sprouts occurred in the lower slope direction where the stump height was relatively high. It was analyzed that lowing the overall stump height was a factor in reducing the occurrence of lateral sprouts. In order to promote the occurrence of high-quality root sprouts, an improved stump cutting, parallel to the slope and close to the ground, would be advantageous.
